The Effects of Diabetes on Your Body

CON EP 74: The Effects of Diabetes on Your Body 

What is Diabetes

Diabetes is a chronic condition in which the body has a problem with turning food into energy.

When you eat food majority of it, for example, carbs, get broken down into something called glucose. Glucose is then used by the body for energy.

Role of glucose

  • Needed for energy and proper cellular function
  • Glucose comes directly from food or is made by the liver (glucogenesis)
  • Glucose hangs out in the bloodstream before being transferred into the cell by insulin
  • When blood sugar is low the liver breaks down glycogen into glucose. 

Role of insulin

  • Produced by the beta cells in the pancreas
  • Insulin is a hormone that circulates in your blood
  • Insulin help cells use glucose for energy

When your body senses an increase in glucose in the blood it notifies the pancreas to produce a hormone called insulin. Insulin then allows your body’s cells to use glucose. Without insulin your body would not be able to use glucose, it is like insulin is the key to the door to let glucose into the cell. 

When you have diabetes your body either doesn’t make enough insulin to counter the glucose or can’t use insulin properly. During this disruption blood sugar stays elevated causing chronic inflammation and leading to other problems like heart disease, eye damage, kidney impairment. 

Currently, there is no cure for diabetes but there are ways to prevent it. Some people are also born with diabetes. 

Diabetes is a chronic dis=sease requiring medication and lifestyle changes, however, when well managed properly the life of a person with diabetes is minimally changed. 

Diabetes facts

Types of diabetes

There are a few different types of diabetes, type 1, type 2, and gestational diabetes. All are dangerous in their own way and can lead to other health-related problems and even death. 

Type 1 diabetes

Type 1 diabetes can affect anyone and it can even start from birth. In type 1 diabetes the pancreas does not produce insulin. The person with type 1 diabetes is going to be insulin dependant because without it cells cannot absorb glucose. 

Type 2 diabetes

In type 2 diabetes either the pancreas cannot produce enough insulin or your body cannot use the insulin properly. Certain people that fall under this category of diabetes can manage their blood sugar with diet and exercise while other people may need medication or even insulin. 

Gestational diabetes

Gestational diabetes is a little different than the prior types. This diabetes affects pregnant women. We are still unsure what causes gestational diabetes but it doesn’t guarantee that the woman will have diabetes after the birth of the baby. Researchers hypothesis that since there are so many hormones at play during pregnancy that sometimes the mother can get insulin resistance while the child develops inside. 

Prediabetes

Prediabetes is a condition of elevated blood sugars but the blood sugar levels are not high enough to be considered in the diabetic range. This is a warning sign, if you don’t start incorporating better lifestyle habits you may become diabetic. 

Effects of diabetes

Long-term complications of diabetes are associated with a chronic inflammatory state. This causes prolonged damage to the blood vessels and organs, the ones that are affected the most are the heart, brain, eyes, and kidneys.

Heart

  • Over time, high blood sugar can damage blood vessels and the nerves that control your heart. People with diabetes are also more likely to have other conditions that raise the risk for heart disease
  • The most common form of heart disease is coronary artery disease. It develops over time as the vessels fill with plaque. Atherosclerosis occurs causing a narrowing of arteries reducing oxygen to the heart causing a weakening and straining of the heart muscle leading to heart attacks and strokes. 

Eyes

Brain

  • Research has shown that there is a link between diabetes and dementia. They don’t have an exact rationale behind it but many things it has to do with the heightened levels of inflammation diabetics have. 
  • Even though your brain is responsible for only about 2% of your body’s weight but consumes about 25% of glucose. Some study’s show a reduction of brain volume of people with type 2 diabetes. 

Nervous system

Kidneys

  • When our bodies digest the protein we eat, the process creates waste products. In the kidneys, millions of tiny blood vessels (capillaries) with even tinier holes in them act as filters. As blood flows through the blood vessels, small molecules such as waste products squeeze through the holes. These waste products become part of the urine. Useful substances, such as protein and red blood cells, are too big to pass through the holes in the filter and stay in the blood.
  • Diabetes can damage this system. High levels of blood sugar make the kidneys filter too much blood. All this extra work is hard on the filters. After many years, they start to leak and useful protein is lost in the urine.
  • In time, the stress of overwork causes the kidneys to lose their filtering ability. Waste products then start to build up in the blood. Finally, the kidneys fail. This failure is called ESRD.

Pancreatic transplant

  • Impact of pancreas transplantation on the patient survival – an analysis of the Japanese pancreas transplant registry 
    • Results: 
      • The survival rates at 1, 5, and 10 years on the waiting list were 98.4%, 90.3%, and 78.1%, respectively, while those after transplantation were significantly improved (p = 0.029) at 100%, 97.5%, and 88.9%, respectively. Furthermore, the survival rates of patients waiting for simultaneous pancreas and kidney transplantation (SPK) at 1, 5, and 10 years were 98.2%, 89.4%, and 75.4%, respectively, while those after SPK were also significantly improved (p = 0.026) at 100%, 94.6%, and 88.8%. The multivariable analysis revealed that the duration of diabetes before surgery was the only independent risk factor (hazard ratio = 1.095, p = 0.012) that affected the patient survival after SPK. 
    • Conclusion:
      •  Pancreas transplantation was found to improve the life prognosis of patients with type 1 diabetes, especially those with end-stage renal failure waiting for SPK.

  • Transplant process
    • The surgeon makes an incision down the center of the abdomen.
    • Next, the surgeon places the donor pancreas on the lower right side of the abdomen attached to the nearby blood vessels.
      • If the pancreas is taken from a deceased donor, then the surgeon removes the pancreas along with a small section of the small intestine.
      • Whereas, if the pancreas is taken from a living donor, the surgeon takes a portion of the body and the tail of the pancreas.
    • The surgeon generally connects the new pancreas to your intestines so its digestive juices can drain.
    • The recipient’s existing pancreas usually remains in their body.
